Abstract

Cet agencement de filtrage pour un téléphone mobile double mode et multibande, notamment pour un téléphone mobile exploitable dans un mode W-CDMA et un filtre coupe-bande qui comprend au moins une résonateur série et un résonateur d'ondes acoustiques en dérivation, est utilisé pour créer une coupure profonde dans la bande de fréquences de réception. Le filtre coupe-bande comprend en outre une pluralité d'éléments inducteurs pour assurer l'adaptation à la capacitance statique des résonateurs à la fréquence passe-bande. Le téléphone mobile peut également être exploité dans les bandes GSM 1800 et 1900. Le filtre coupe-bande est fonctionnellement connecté à un filtre d'harmoniques afin d'éliminer la troisième harmonique des ces bandes GSM. Le téléphone mobile peut également être exploité dans la bande GSM inférieure, dans laquelle un filtre d'harmoniques peut partager une voie d'antenne avec le filtre coupe-bande.
